Yes.... I'm afraid I'll never know for sure what downed my aircraft. Can Futaba 2.4GHZ signal be jammed in order to cause this ?

Correct, first time I triggered the safe mode as I always do soon after takeoff. The second time was to try t prevent the crash. Yes I sent the log to XAircraft but have not received a reply yet. No I have not powered the quad since the crash because the wiring between motors and ESC's is a...

Yes the FC was secured to the frame. But I wasn't able to find the GPS antenna no where near the crash site. I suspect that maybe the antenna came off and one of the props cutoff the cable. Could that caused to loose control like that?

I had been flying for about 10-12 minutes doing some mix flying. Then I decided to climb to about 110 meters while on attitude mode. After climbing and holding altitude for a few seconds I noticed that the quad was not responding to any control inputs. Then it decided to fly in one direction...

That safe mod activation was on purpose, I always like to tested right after takeoff. The last activation was a last effort attempting to save the quad, out of desperation.

No worries Andy, when the crash took place I was flying in Attitude mode which means that the XAIRCRAFT FC was relying on onboard gyros and barometer sensors to keep control. Throughout the flight I had 13 satellites lock in. However when I realized that something was wrong I did activated the...

Hello everyone, I need assistance in pinpointing probable cause of crash, below is the black box log file for the flight: http://log.xaircraft.cn/#2015_06_13_100521.429_76.1.06.07 http://log.xaircraft.cn/report.htm#2015_06_13_100521.429_76.1.06.07 Any help will be greatly appreciated

Andy thank you for your opinion! So far the radio receiver is able to bind with transmitter, the motors are rotating freely, I still need to run a few batteries thru them to see how they perform. The FC however in order to tested I will need a new GPS/compass antenna to the tune of $140, I would...

So yesterday I sadly lost my beloved Align M480 with SuperX on a violent crash. My question is should I use the SuperX on the new build? Should I just discard it? How can I test its integrity/functionality? I will be building a Skyhero 700. I suspect the cause of the crash was GPS antenna came...

Good evening gent's! I'm thrilled to report that I've figured out what was the problem, it was a rookie mistake on my part. You see, when putting the quad back together I mistakenly switched the rear two motors around without realizing it, that right there inverted the correct rotation of the...

Yes I've always used airplane profile just like the Caircraft setup video suggest. Also just got back from testing the newly programmed radio, still same results. I have two options left on my troubleshooting quest, 1. Remove the SBus plug and try regular servo wires for aileron, elevator...

Guys I really appreciate all your inputs!! Hexacrafter, I did check my Futaba 14SG, and all rudder trims & subtrims were all 0. I will however follow your advice and completely reset my radio back to factory settings and start from the beginning. Now, I m using the SBus connection between the FC...

Darson thanks for responding, I'm not too familiar with some of the terminology that the black box displays, do you know what does that "G" gain @123% represents? Since I've been trying to resolve this for three days now, I went ahead and reset back to default all settings on both the FC and...

Already calibrated ESC's twice, they were all correctly calibrated.

Jwoike, question, on the test flight I recorded while testing the quad, I noticed that the quad would not respond to any rudder inputs, but it would respond as expected when applying any other control movements. Now, considering that the FC is able to hold altitude and position, what do you...

Ok, so how can I fix that?

The compass on the Super X is inside the GPS puck correct? Funny you mentioned that, I've also noticed that the controller takes longer to lock on to satellites. What's frustrating is that this thing was working fine before I had to relocate the ESC's, in fact I never messed with the GPS or...

Andre here is a short video I took this morning: Keep in mind that all the yaw movements are not due to any redder inputs done by me, in fact the quad is completely unresponsive to any rudder inputs. Black box: http://log.xaircraft.cn/report.htm#2015_05_03_061320.069_49.1.01.57...

Amerly, yes my motors are perfectly aligned, but even if they werent I doubt that unbalanced motors could be the cause of my particular problem, check the video below and black box. Notice that all the yaw movements the quad made inflight were not the result of any inputs from the radio, it was...

That's what I'm afraid of.
